Treat changing the graphics adapter the same as changing the backend

This results in the list of available antialiasing modes being updated; before, it would only show the modes available for the adapter that was selected when the graphics window was opened (or the backend was last changed).

The list of available modes is updated by `GraphicsWindow::OnBackendChanged`'s call to `VideoBackendBase::PopulateBackendInfoFromUI`, and then `EnhancementsWidget::LoadSettings` updates the UI.  Both of these are connected to the `GraphicsWindow::BackendChanged` signal.
